JAMES JOSEPH KEON, OF GIVEN SOUND, ONTARIO, CANADA, ASSIGNOR TO THE WIL- LIAM KENNEDY & SONS, LIMITED, OF OWEN SOUND, CANADA.

, STOPLOG WINCH.

Application led September 18, 1925. Serial No. 57,127.

To all whom 'it may concern:

Be it known that I, JAMES JOSEPH KEoN, of the city of Owen Sound, in the county of Grey, Province of Ontario, Canada, a subject of the King of Great Britain, have invented certain new and useful Improve ments in Stoplog -VVinches, of which the following is a specification.

This invention relates to winches such as used in connection with dams for removing logs which are used for controlling the height of water. These dams include a series of spaced concrete piers arranged across the stream, said piers being grooved or recessed to receive a series of logs which extend from pier to pier to complete the dam. By removing or replacing one or more of these logs, the level of the water may be lowered or raised as the case may be, and it is to the winches which are used for removing these logs thatmy invention relates. As the posts or piers are often placed irregular' distances apart it has been necessary in a complete installation to supply winches of various lengths, which increases the cost of making the complete installation very materially.

-My object is therefore to devise a winch which may `be adjusted to any desired length within the limits of the device, thus enabling a standard winch to be used for all positions, its length being adjusted when the winch is being installed, or if the winch be mounted on a track extending across the dam, theA same winch may be used for all the sections, the length of the winch being adjusted as may be necessary to suit the distance between piers.

I attain my object by means of the constructions hereinafter described and illustrated in the accompanying drawings in which- Fig. 1 is a winch; n

Fig. 2 is a sidev elevation of the same; and

Fig. 3 an end elevation of the same.

In the drawings like numerals of reference indicate corresponding parts in the different figures.

The device comprises a frame formed of two sections A and B slidable longitudinally of one another whereby the length of the frame may be varied as desired.

The section A comprises a pair of longitudinal frame members 1 of channel Section plan view of my improved connected together by transverse frame members 2, 3, 4, 5, 6 and 7 and 8', while the section B comprises a pair of longitudinal frame members 8 connected together by transverse frame members 9, 10, 11 and 12. The frame members 8 are spaced apart so that they will receive between them the longitudinal frame members 1, guides 13 being formed in which the ends of the members 8 are slidable and by means of which said frame members 8 are held in alinement with the frame members 1.

The left hand end of the frame, having reference to Figs. 1 and 2 vof the drawings,

is supported by means of a bogey truck 17V of any suitable type, which truck is connected with the transverse members 2 and 3 connecting the inner frame members 1.

The right hand end of the frame is supported by means of a similar bogey truck 18., which truck is connected with the transverse frame members 9 and 1() which con-V nect the outer frame members 8. In practice suitable tracks will be provided on which the wheels of the trucks will run.

The winch will be provided with a pair of hoisting rams 19 and 20, one adjacent each end of the frame. For adjusting the frame to vary the distance between the rams and the distance beween the trucks, I mount on each of the inner frame members 1 a rack 14 with which meshes a pinion 15 fast on a shaft 16 journalled in suitable bearings on the outer frame members 8. This shaft is provided with a squared end on which a suitable crank may be fitted for rotating the shaft or may be rotated by motor power by means of suitable gearing.

'Ihe outer frame members 8 will be of such a length that when the frame is adjusted so that the rams and trucks are at their maximum distance apart the end of the members 8 will rest on the transverse frame members 3 directly over the bogey truck 17 and the inner frame members 1 will be of such a length that when the frame is adjusted so that the rams and trucks are at their maximum distance apart the ends of said members will rest on the transverse frame members 9 and 10 directly over the bogey truck 18. There is there` fore no danger of the center of the frame sagging as would be the case if the longitudinal frame members of one section were not of sufficient length to reach over the truck of the other section when the rams and trucks are at their maximum distance apart.

The hoisting-rams V19 and 20 carry as usual at their lower ends hooks 21 by means of Which the stop logs are engaged and lifted. As the object of my invention is to provide a construction in Which the distance apart of these rams may be varied as desired, the ram 19 is vertically movable in a frame 35 carried by the transverse members 11 and 12 and a suitable guide 22 for its upper end is supported by means of braces 23 secured to the longitudinal frame members 8.

The ram 2O is vertically movable in a frame 24 carried by the transverse members t and 5 and a suitablel guide 25 for its upper end is supported by means of braces 2G secured to the longitiulinal frame members l.`

Each ram, as is common in the art, is provided With a rack whereby it may be raised or lowered by means of a suitable pinion 27. The pinion 27 for the ram 2O is mounted o'n a shaft 28 which is connected by a train of gears to shaft 28, which shaft driven by means of a suitable gearing 2S) from a main drive shaft 30. The mechanism for driving this main drive shaft is supported by the longituidnal frame members 1, and therefore there will at no time be a variation of distance between the said driving mechanism andthe ram 20. The 'ram 19 is actuated by means of a pinion 31 driven by means of suitable gearing 32 from a shaft 38 driven by suitable gearing 231il and 29 from the `main drive shaft 30. Owing to the variation in position of the ram 19 relative to the driving mechanism, the shaft 33 is therefore preferably formed for a part of its length of square cross section and the pinion 32a of the gearing 32 is arranged to slide longitudinally thereof. Other arrangements than that shown might, however, be devised to permit of longitudinal movement of the pinion 32a on the shaft 33 but preventing rotary `movement of the pinion relative to the shaft.

A motor may be provided for driving the main drive shaft 80, or manually operated means, or both as is common in the art.

From the above description it Will be seen that I have devised a Winch which Will satisfactorily attain the object of my invention as set out in the preamble of this specilication. When it is desired to adjust the length of the Winch, it is merely necessary to apply a suitable crank to the shaft 1G and rotate the shaft in the desired direction or suitable gearing may be provided so that shaft 16 can be rotated by means of the hoisting motor on the Winch, if a motor provided.
